You took one sentence out of context- what is this, TMZ? Lazy commenting. The full context of that sentence was
“On the best of days, I block distractions. My life is optimized for deep work. I get tons of things done. I look back at the day and feel satisfied. I’ve created more than I’ve consumed. I play like a professional.
Even the best of us give into the temptations of the amateur.”
Meaning its a struggle for the author as well. Your reading comprehension needs work.
